The Broncos finished the season 10–3 and 5–1 in conference to win their first Big West title. In their fourth season in Division I-A, the Broncos were invited to their first ever bowl game, the Humanitarian Bowl on their home field, where they defeated Louisville, 34–31. Boise State won all eight games played on the blue turf of Bronco Stadium in 1999.
